Used Alde 12v DC heating pump Model 2928420 for header tank, used only for 2 seasons before changing. Removed from Swift Challenger 580 caravan, replaced this pump with inline circulation pump fitted on the side of heater unit. I’ve tested to confirm pump works. Also have rubber U bend and aluminium Alde 22mm dia pipe for same heating system, if of any use let me know and I will include, parts removed from install of the inline pump.
